At first glance, you’d be forgiven for mistaking this image as a watercolour painting.
But the image is very much real, and was snapped by photographer Juan Carlos Casado in Tenerife earlier this month.
The photo, which was featured as NASA ’s Astronomy Picture of the Day, shows the Mount Teide volcano , alongside its perfectly triangular shadow in the sky behind it.
Strangely, despite casting a triangular shadow, Mount Teide itself does not have a strictly pyramidal shape.
NASA explained: “The triangle shadow phenomena is not unique to the Mt. Teide, though, and is commonly seen from the tops of other large mountains and volcanoes.
“A key reason for the strange dark shape is that the observer is looking down the long corridor of a sunset (or sunrise) shadow that extends to the horizon.
“Even if the huge volcano were a perfect cube and the resulting shadow were a long rectangular box, that box would appear to taper off at its top as its shadow extended far into the distance, just as parallel train tracks do.”
The volcano isn't the only exciting thing to look out for in the image though.
The photo also features a stunning view of a full moon , shortly after its total lunar eclipse.
